N/Z effect on reaction mechanisms cross sections in the $^{78}Kr+^{40}Ca$ and $^{86}Kr+^{48}Ca$ collisions at 10 AMeV
Résumé
Nuclear reactions between medium-mass nuclei at low energy are characterized by the competition between binary and evaporation process in the compound nucleus de-excitation. A study of the influence of the neutron richness of the entrance channel on the decay paths of the compound nuclei formed in the (78) Kr +(40) Ca and (86) Kr +(48) Ca at 10 MeV/A is presented. The experiment has been performed at Laboratori Nazionali del Sud by using the CHIMERA 4π multidetector for charged particles. The Kinematical characteristics of the two reactions support the conclusion of a production via long lived system. Besides the results relative to the n-poor system are compared to those obtained at GANIL, performed at 5.5 AMeV, in order to study the energy influence.
